EGABLANK.DOC
This is the screen blanker for the EGA described in PC Magazine, Sept 30, 1986,
page 302 & 303 in Charles Petzold's column PC Tutor. It blanks the EGA with
either a monochrome or a color monitor for about 7-1/2 minutes. The time to
blank is set in the line reading:
MOV WO [010A],2000
Change the 2000 (in hex) to obtain other time delays. A value of 1 will blank
in 55 milliseconds -- a value of 0400 will take about 1 minute, and a value of
FFFF will take about an hour.
Create the .COM file with:
